Bumps are where it's at. There is nothing like hitting Stowe or Sugarbush late in the season, when the groomers are running over 2% of the terrain and everything - especially the steeps like Star, Goat, Steins, or Ripcord are full of bumps the size of volkswagons and the snow is soft and forgiving. Moguls are like a giant terrain park with a thousand features and every time you ride through it, there's a new line to try. Personally, I put away the hardboots for this just because I feel more comfortable with my softies. Balance is key - a snowboarder's center of gravity should be just like a good mogul skier's - very little movement, which can be tricky if you find yourself setting hard turns.
Right now, CT has had very little snow. Our local mountain has a mogul run but the bumps are very hard and icy in between. Natural snow helps a lot, warm weather does, too. You guys near areas with large snowfalls are sooo lucky. Soft bumps all the time!
